SJCL ecc encrypt/decrypt

crypt.js

var data = {
    herp: "derp"
};

//Make the keys.
var temp = sjcl.ecc.elGamal.generateKeys(384, 1);

//to encrypt with publickey:
var pubjson = temp.pub.serialize();
var point = sjcl.ecc.curves["c" + pubjson.curve].fromBits(pubjson.point);

var publicKey = new sjcl.ecc.elGamal.publicKey(pubjson.curve, point.curve, point);
var symkey_obj = publicKey.kem(0);

var ciphertext = sjcl.encrypt(symkey_obj.key, JSON.stringify(data));
var message = JSON.stringify({ 'ciphertext': ciphertext, 'encrypted_key': symkey_obj.tag });
// and message gets saved off

//to decrypt with privatekey/recovering "message"

var cipherMessage = JSON.parse(message);
var secjson = temp.sec.serialize();
var ex = sjcl.bn.fromBits(secjson.exponent);

var privatekey_obj = new sjcl.ecc.elGamal.secretKey(secjson.curve, sjcl.ecc.curves["c" +secjson.curve], ex);

var symkey = privatekey_obj.unkem(cipherMessage.encrypted_key);
var decryptedData = sjcl.decrypt(symkey, cipherMessage.ciphertext);

I'm also interested in an updated version of this. serialize() is no longer part of the ecc library

var sjcl = require('sjcl');

var data = {
    herp: "derp"
};

var curve = sjcl.ecc.curves.c384;
var temp = sjcl.ecc.elGamal.generateKeys(curve, 1);
var pub = temp.pub.get();
var sec = temp.sec.get();

var pubObj = new sjcl.ecc.elGamal.publicKey(curve, new sjcl.ecc.point(curve, sjcl.bn.prime.p384.fromBits(pub.x), sjcl.bn.prime.p384.fromBits(pub.y)));
var secObj = new sjcl.ecc.elGamal.secretKey(curve, sjcl.bn.prime.p384.fromBits(sec));

var ciphertext = sjcl.encrypt(pubObj, JSON.stringify(data));
var message = JSON.stringify({'ciphertext': ciphertext});

var cipherMessage = JSON.parse(message);
var decryptedData = sjcl.decrypt(secObj, cipherMessage.ciphertext);
console.log(decryptedData);
